Tokyo (Reuters) - the majority of Asia bags ceded and the euro fell on Thursday once the European Central Bank said that it would not accept Greek bonds as collateral, a strong response to the efforts of Athens to renegotiate the terms of the bailout with creditors.

The appetite for risk, which had stoked earlier this week by expectations that Greece would quickly gain relief from their creditors, was cooled once the ECB abruptly withdrew his gentle treatment of the Greek debt and canceled its acceptance of the bonds of the country as a guarantee.
